With Muller riding high on confidence after taking down the tournament favorite and Auger-Aliassime finding solid form, this quarterfinal is shaping up to be a compelling clash. Will Muller continue his inspired run, or will the Canadian take control of this rivalry?

Felix Auger-Aliassime vs. Alexandre Muller Preview

Auger-Aliassime showed brilliant moments early in the season, starting strong with a title in Adelaide over Sebastian Korda. Followed by another at the Open Occitanie in a tight three-setter against Aleksandar Kovacevic. He added a semifinal in Qatar and a finals run in Dubai, falling to Stefanos Tsitsipas in straight sets.

However, his momentum has since faltered, with Hamburg marking his first notable run in weeks. Statistically, he’s been dominant on serve, with 276 aces and 74% first-serve points won, but his 30% break point conversion (231 opportunities) highlights the inconsistency that’s crept into his game.

Muller kicked off the season with a breakthrough title in Hong Kong, beating Kei Nishikori in three sets. While his year has been up and down, he’s had moments of promise, reaching the Rio final, a Challenger semifinal in Cap Cana, and a quarterfinal in Marrakech. Since then, however, early exits have returned. His numbers tell the story of a streaky but dangerous contender: 86 aces, 67% first-serve points won, and a solid 41% break point conversion rate from 172 chances.
